A Mesoscale Convective System across Arkansas produced a gust front which was moving southwest across the Middle Red River Valley of Southwest Arkansas, Southeast Oklahoma and Northeast Texas. This gust front intersected a weak surface frontal boundary across North Texas north of the Dallas Forth Worth Metroplex to near Texarkana, Texas.

The episode as NWS SHV wrote it up.
A Mesoscale Convective System across Arkansas produced a gust front which was moving southwest across the Middle Red River Valley of Southwest Arkansas, Southeast Oklahoma and Northeast Texas. This gust front intersected a weak surface frontal boundary across North Texas north of the Dallas Forth Worth Metroplex to near Texarkana, Texas. Atmospheric instability was still significant enough during the late evening hours of June 23rd for the developing of strong to severe thunderstorms. One of these storms produced enough wind to down trees in Red River County, Texas.
The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Shreveport, LA wrote its last area forecast discussion before the first event at Jun 23, 6:27 PM CST, 2 hours 30 minutes earlier.
Area Forecast Discussion National Weather Service Shreveport LA 727 PM CDT Fri Jun 23 2017 .AVIATION... For the ArkLaTex, VFR for now, but a convective complex is looming to our N from near KDEQ to KLLQ in AR. This feature will have life potentially all night as a cold front is draping in as well. This TS activity will likely be affecting AR sites and perhaps LA TAFS as well during the late evening and early morning. The cold front will filter N/NE low level winds just as the morning stratus is lifting after daybreak and may crop up some early convection. Improvements back to VFR may take time in the afternoon on Sat. /24/ && .PREV DISCUSSION... /issued 338 PM CDT Fri Jun 23 2017/ DISCUSSION... The remnants of Tropical Depression Cindy may have shifted well north and east of the Four-State Region today, but in its wake, a rather moist atmosphere ensued. In fact, SHV 12Z sounding showed a PWAT of 2.28 inches which is quite impressive. This tropical-like environment coupled with a mid-level shear axis and a 300-500 m2/s2 0-3 km SRH axis resulted in lingering scattered showers /moderate to heavy rainfall makers/ and a few thunderstorms across portions of southwest AR and north central LA earlier this morning. Some of the storms became strong to severe, with wind the primary threat. The mid-level shear and SRH axes have since waned and thus so has the precipitation. Current radar analysis showed the tail-end of a line of storms stretching from southern LA to across the Tennessee Valley that have brushed across our far southeast zones late this aftn. Furthermore, an MCS was propagating southwest across southern MO to across northern AR late this aftn along a southeastward moving cold front. Isolated showers and thunderstorms have struggled to develop across southwest AR given the airmass is likely worked over from the earlier convection. However cloud cover has thinned across portions of east TX, deep east TX and southeast OK, which therefore allowed for temps to warm into the lower 90s which could garner isolated showers/thunderstorms. In addition, with dewpoints in the lower to middle 70s, there are concerns for heat index values increasing to between 100-105 for some locales across east TX this aftn, which is one-half of our Heat Advisory Criteria. The second-half of our Heat Advisory Criteria is that these warm and rather moist conditions combine for heat index of 105 or greater are expected for consecutive days which is not the case, but more on that in a bit. Temps remained in the 80s elsewhere given the extensive mid-upper level cloud cover within a tropical-like environment. Attention will turn to a broad UA trough that has extended from southern Canada southwest to across the Northern Plains and to near the Central Plains late this aftn. A 1020 mb sfc ridge across the Southern Rockies was pushing a cold front southeast across the Panhandles and Southern Plains with it encountering the Ouachita Mountains hence right on our doorstep. It is this same front that has generated the MCS to our north. Sfc winds have veered to the northwest across Pittsburg county in southeast OK, likely a pre-frontal feature, whilst Choctaw county in far southeast OK has a calm wind, which at times occurs before a wind shift. The timing for the impingement of the front is still of much debate between the quicker NAM and the slower GFS. This time of year, it is usually hard-pressed to get a cold front let alone having a quick propagation as suggested by the NAM solution (the NAM pushes the front through the entire CWA by mid-morning Saturday versus just south of the I-20 corridor per the GFS/. Will elect to lean towards the GFS depiction of the front and as such, the MCS will continue to move southeast likely not affecting the region, but additional storm development along the front will affect the area. The precip will impact the far northern zones between 24/00-03Z, nearing the I-20 corridor between 24/09-12Z and spread to the remaining areas by mid to late morning. Per the GFS, the front will clear the southern zones by late Saturday aftn/early evening and will slowly see precip wane from north to south as the fropa ushers in a drier airmass. Model guidance hints at 0-6 km bulk shear values of 30-50 kts across southeast OK and portions of southwest AR and extreme northeast TX this evening, suggesting that some storms could become organized and produce gusty winds /primarily/ and intermittent large hail. The 0-1 km helicity values are projected to be rather weak so attm, the threat for tornadoes will be rather low. Nonetheless, the existence of a frontal boundary still raises concern for the plausibility of an isolated tornado given the right local environmental circumstance, so can not discount it completely. The cold front will also cause daytime temps to drop into the lower- middle 80s tomorrow /some 8-10 degrees below norm/ which mitigates the issuance for a Heat Advisory. Precip will linger across the southern-half of the CWA through Monday morning during which time the front will be rather diffused and sfc ridging near the region will maintain a drier airmass. Thereafter a typical summer-time pattern will take place with diurnally driven sea-breeze convection nearing/moving across the southern-half of the FA each aftn on Wednesday-Friday. Flow aloft will back from the northwest to the southwest by the end of the week, courtesy of a northeastward moving UA low across the Northern Plains. Its southern periphery could brush across our northern zones late week/early weekend and perhaps generate showers and thunderstorms. && .PRELIMINARY POINT TEMPS/POPS...

With the remnants of Tropical Storm Cindy having moved well north and east of our region today, much of the rainfall associated with Cindy will move north and east with her. However scattered showers and a few thunderstorms lingered across portions of southwest Arkansas and north central Louisiana late this morning, with a few storms approaching strong levels. A gradual eastward shift of the precipitation exiting the region will take place by this afternoon. The lack of scattered showers and thunderstorms will be temporary as a cold front will begin moving into the Middle Red River Valley of Northeast Texas, Southeast Oklahoma and Southwest Arkansas this evening. Along with this frontal boundary will be scattered to numerous showers and thunderstorms and this activity will build southward towards the Interstate 20 Corridor of Northeast Texas and Northern Louisiana late tonight. Some of these storms could become strong to severe overnight, with damaging wind gusts and large hail will be the primary threats. .DAYS TWO THROUGH SEVEN...Saturday through Thursday... Scattered to numerous showers and thunderstorms in association with a cold front will effect most of the Four State Region during the day Saturday before the activity tries to push southward and taper off Saturday Night into Sunday along with the cold front. Low chances for showers and thunderstorms will remain in the forecast through early Monday mainly along and south of the I-20 Corridor as well. Otherwise, we should see a drying trend through the early part of next week with low rain chances returning once again by the end of the upcoming work week. .SPOTTER INFORMATION STATEMENT... Activation of emergency management personnel...amateur radio operators...and storm spotters may be needed tonight.
